Advice for Building Owners

 

Our Portland construction cost index increased 2.2 percent overall in 2020. Downward pressure continues as some trade contractors and suppliers work to rebuild their backlogs. However, due to pandemic-related disruptions to supply chains we are seeing significant increases for PVC, steel, copper, lumber and glass. This, together with losses in productivity due to ongoing COVID-19-related procedures will offset much of the downward pressure in the market. We recommend planning for project costs to increase 3% in 2021.
